Posted by mtk52983 on Thu Feb 28 22:25:34 2008, in response to TA is obsessed with CBTC, and "New" tech for no reason., posted by JournalSquare-K-Car on Thu Feb 28 22:08:34 2008. Carbon steel rots and eventually the cost of maintaining older equipment is greater than the revenue they produce. New cars are heavier because of additional federally mandated safety features. MTA does not need to retain old cars to improve the subway system. Signals are necessary to prevent trains that are stopped from being targets of other trains or around curves so the T/O can keep the train at a safe speed. That being said, there are far too many timers in the system and that makes headways much greater than they need to be. Moscow can run subways on 90 second intervals with long stretches of no express stops, why can't New York City? While New York City does have longer dwell times the number of TPH is below what it could be |
